HOTTER than Mariah Carey : CAT 5 Phase Out Special -- All cables $0.50 each **up to 25 ft**

[Dug]

I'm a Sound Engineer by profession and I'm almost offended by this thread, no link, but twisting the cables provides shielding to NO forms of noise AT ALL....

Also, no speaker cables don't need to be shielded

Sorry- I got that out of Network+ Guide to Networks book on UTP.
"The more twists per inch in a pair of wires, the more resistant the pair will be to all forms of noise"

Oh btw. Here's a link to hundreds of other links discussing among other things, interference in speaker cables.

Jon Risch's Web Site

So far every website I've found explains UTP in the same way.
"The wire pairs are twisted because it helps reduce crosstalk and noise susceptibility."
BTW this is not a technical forum. shield, resist, protect, etc is all the same to me. If you want to be technical, go to that forum.

More on noise

and even more

speaker wire and power

Oh and sorry to almost offend you big guy.

Twisting does provide some immunity to noise - the reason why is because you have a differential signal between both wires. If the cable runs past a particular source of noise, the twisting of the wires generally means that particular noise source will affect both wires equally, so the differential signaling is still preserved (ie the difference between the signals on wires A & B).

However, I think an audio application might be a little more affected, since the "-" wire may not necessarily be at "ground" when you start adding noise - the difference between the "-" & "+" wires (A & B wires) will remain the same, but if the "-" wire might change voltage relative to ground, which might cause some distortion or other audible noise.

Just my $0.02!

well, I read your four first references, the first one its just a link to other refrences, so i just left it like that.

the other three references, agree with me, a couple of quotes from your links

from epanorama.com:

Thightly twisting of balanced signal conductors help to make average distance of each conductor to any doutside magnetic field source the same.

tightly twisting of BALANCED signal conductors, as i said, twisting has no effect in an unbalanced signal and is talking about line level, not speaker level signlas.

from engineeringharmonics.com:

1.2.2.2. Balancing and Twisting.... Together these two techniques provide substantial EMI immunity in interconnects

Together being the key, though it also states there's effect of just twisting, it's talking about line level signals.

the 7volt.com probably agrees with me the most, my main point was that gauge 30 wire was to thin, which is the main point of this page, about the 110v ac thing, it says "Is it enough to worry about? I don't know", as I said interference happens, if it was relevant in speaker cables you'd hear it with the amp of.

so, OK sorry about the offese thing, I was kidding, I really hate it when the forums just become flame wars, just tryin to help out.

Before this topic hits the graveyard, it's worth noting that the original idea of using an entire cat5 cable as a positive leg (all 8 wires paralleled), and another cat5 cable as a negative leg, is not the same thing as twisting wires to avoid inductive interference. This is simply creating some loosely stranded speaker wire. Twisting those combined clumps of already-twisted copper wire might/might not have an effect (I have already stated my opinion), but there's no real reason to twist wires inside of bigger wires, if all the wires are carrying the same signal.

This deal is NOT as hot as it seems!
I ordered 5 Each of 12 different combinations of colors and lengths from 2' to 25' for a total of 60 cables.
I got 60Cables, Black, 10'

that's terrible. thanks for the update.

Same thing happened to me. I ordered 20 25' cables and they sent me 20 14' cables. :|

Why would u care if Mariah Carey is hot or not? She can sing and her songs are great and that's good enough to be singer. You can't ask too much from one person.
by the way, the cable is pretty good deal.

What is the difference between normal Cat5 and this 110 stuff they have?

 

[Reel]

They are sold out.

Mariah? or Cat? Unbelivable.

 

[Kwad Guy]

If these guys are substituting colors, well no biggie. But if they are substituting lengths, then
that, and they, suck. Big time.

Time for a big crap rating on resellerratings!
